'Ihe melted solder engages the walls of the intermediate portion and securely fastens the wire meshes to the intermediate portion when cool.

The core member I3 is positioned in the shell I2 with the front wall 26 thereof spaced from the front of the shell and the sides 28 thereof spaced from the sides I5 of the shell. The shell I2 in the interior thereof adjacent each side I5 includes side wing walls 36 which are spaced from the side walls I5 and are suitably secured to the side walls 23 of the core member I3 to retain the core member I3 in the shell I2. The wing walls 36 each includes an outwardly extending rear Wall 37 which is suitably secured as by welding to the wall I5. The rear walls 3'I are positioned in the rear of the side apertures I'I of the shell I2. l(See Fig. 3.)

Spaced in the rear of the intermediate portion 22 ofthe core member I provide a wall 38 which extends from one wing wall 3'I to the other and from the upper tank portion 28 downward below the top of the lower tank portion where it includes a downwardly and forwardly inclined portion 39 which is spaced below the bottom of the lower tank 2i. The wing walls 36 extend from 30 the upper tank portion 2K3 downward to the inclined portion 38. (See Fig. 2.) Intermediate the upper and lower tank portions 20 and 2| the wall 38 has a circular aperture 38' therein.

Approximately in the same plane with the upper surface of the lower tank 2l and intermediate the Wall 3S in the tank 2|, I provide a shutter member 48 which is pivotally mounted at the rear thereof -on a rod 4I which is supported by the Wing walls 36.

On the under side of the upper tank 20 I suitably mount a thermo-responsive arm 42 which is made of bimetal. The upper end of a rod 43 is pivotally connected to the arm 42 as at 44, and the lower end of the rod 43 is pivotally connected to the shutter 45 as at 45. The arm 42 is constructed so that when it is cool it is curved downwardly as shown in Fig. 2, and when it becomes heated it rises upward, thus it will be seen than when the arm 32 rises upward the rod 43 will move therewith and swing the shutter 40 upward.

In operation the return conduit 24 is suitably coupled as at 45 to the water jacket outlet conduit 4l of a water cooled engine 48 and the outlet conduit 25 ofthe radiator is suitably connected to the water jacket inletxconduit 49 of the engine 48. The radiator is positioned so that the fan 5I of the engine 48 is approximately positioned in the aperture 38 of the wall 38. When the radiator core i3 and the water jacket of the engine 48 are lled with water andthe engine 48 is started, cooling air enters the shell aperture I 8 and circulates around the front and sides of the radiator as shown by the arrows in Fig. 3.

When the temperature of the water in the radiator rises to a predetermined degree, the thermoresponsive arm 42 starts to move upward, thereby moving the shutter 40 upward through the medium of the rod 43 whereupon the engine fan 5I draws cooling air through the shell aperture I6. This air is directed upward by the inclined wall 39 past the shutter 4I) and circulates over the rear of the intermediate portion 22, and

is then drawn out of the l,core member I3 through the aperture 38 in the wall 38 and directed onto the engine 48.

When the engine 48 is stopped and the water in the radiator cools to a predetermined degree the thermoresponsive arm 42 moves downward and through the medium of the rod 43 swings the shutter 4I) to a closed position.

From the foregoing it will be seen that when the cooling water is cold the shutter 48 is in a closed position and prevents the engine fan 5I from throwing cold air onto the motor, thus the motor will quickly heat to a running temperature, whereafter the thermoresponsive arm 42 actuates the shutter 48 to retain the cooling water in the motor at a suitable operating temperature. As the water circulates from the upper tank 28 downward through the intermediate portion 22 to the lower tank 2I the wire mesh members 32 and 33 absorb the heat of the water and the wire mesh member 32 conveys the heat to the front wall 25 and through the front wall to the mesh member 33 and as air circulates through the mesh member 35 it is cooled. At the same time the mesh member 33 conveys heat to the rear Ywall 2l and therethrough to the mesh members 34 and 35. Furthermore, the Wire mesh members 32 and 33 form a tortuous passageway for the water to circulate through, thus thoroughly agitating the water as it circulates from the upper tank to the lower tank.

In Figs. 6, '7, and 3 I have indicated one of my improved radiators generally at 52. The radiator 52 is shown as operatively installed on the vehicle 53 wherein the vehicle engine 54 is positioned transversely of the longitudinal frame 55 of the vehicle. The radiator 52 is similar to the radiator I0 and like portions thereof are indicated by similarly primed reference numbers.

The radiator 52 is positioned with the front wall 26 thereof adjacent one side wall 55 of the vehicle 53 and as shown in Fig. 8 the wall 55 has a plurality of apertures 58 therein with vertical louvers 59 adjacent the rear of each of the apertures 58. The louvers 59 are inclined outwardly towards the front of the vehicle 53 so that when the Vehicle is in motion they direct air through the apertures 58 onto the front wall 25 of the radiator 52.

The rear wall 58 of the vehicle has an aperture 8| therein for the emission of air.

Below the shutter 48 I provide an air scoop 52 which includes side walls 83 and 54 and a bottom wall 65. The bottom wall 85 is inclined downwardly towards the front of the vehicle 53 and takes the place of inclined wall 35 of the device I. The inclined wall 85 of the device 52, like the inclined wall 39 of the device I8, directs air upward onto the rear of the intermediate portion 22 of the radiator when the shutter 48' is open. The operation of the radiator 52 is the same as previously described in connection with the radiator I8.

In Fig. 9 I have indicated an automobile generally at lil. rIhe automobile III is of the streamlined type and includes a body portion II having sides 'I2 and a top 'i3 which at the rear is inclined downwardly to form a back portion 14. Furthermore, the automobile 'I5 is of the type wherein the engine is positioned at the rear of the passenger compartment and, as shown in Fig. 10, includes an engine l5 which, like the engine 54 shown in Fig. 6, is positioned transversely to the longitudinal axis of the automobile. Although shown as positioned transversely to the longitudinal axis of the automobile `of the automobile.

primed reference numerals. Theradiator 'i6 is positioned adjacent one`of` the sides l2 of the automobile body and the radiator 11 is positioned adjacent the other side.

Adjacent the radiators 'IG andll each `side 12 "of the bodyll has an aperture' therein. The

apertures 18 are of the same shape and area as the intermediate conduit portions 22" of the radiators.

The radiators 16 and 11 are positioned with the outer mesh members 30" thereof ilushwith the outer surface of the adjacent side wall 'l2 of the automobile body 1I as clearly shown in Fig. 10. The radiator 16 is shown as positioned adjacent the fan end of the engine 15 while the radiator 'il is at the oppositev end of the engine and has the wall 38" omitted therefrom. As shown in Fig. 10 the upper tank conduit 24 of the radiator 'i6 and the upper tank conduit 24 of the radiator 11 are connected by a conduit 19. The lower tank conduit 25 of the radiator 76 communicates through a conduit 8i) with the bottom of the engine water jacket, and the lower tank conduit 25 oi the radiator 11 communicates through a conduit 8l with the top of the engine water jacket.

When the engine 15 is operating the water circulation is from the-lower tank 2l" of the radiator `'Iii through the conduits 25 and Sil into the water jacket of the engine, thence out of the water jacket and. through the conduit 8| and through the conduit 25" of the radiator 11 into the lower tank 2| of the radiator 11. From the lower tank 2l" of the Yradiator 11 the hot water rises through the intermediate conduit portion 22" thereof into the upper tank 20 thereof. From the upper tank 20 of the radiator 'l1 the water flows through the conduit 24 thereof and through the conduit 19 and the conduit 24 of the radiator 1li into the upper tank 2i!" thereof and thence downward through the intermediate portion 22 into the lower tank 2 I.

With this type of installation a portion of the rear wall 'i4 of the automobile vbody 'H is preferably hinged as indicated at 82 to form a `door 83 in which-a plurality of horizontal louvers 84 are provided for the passage of air from the engine compartment.

In Fig. 11 I have indicated a slightly modified form of construction of the intermediate conduit portion of my radiator generally at 85. As shown,

the conduit portion 85 is formed similar to conduit portion 22 and includes spaced front andrear walls t@ and 81, and` end walls` 88. The front f wall` S5 is plane `while the rear wall 81 is formed with a plurality of vertically extending crenela-l tions` 8S, each of which includes spaced side walls 9i! and a rear wall 9i. i t

Positioned on the' front wall `86 I provide a wire mesh member 92 which is formed in a serpentine shape. The wire mesh member 92, like the previously described wire mesh member 3Q is of the type wherein the vertical and horizontal strands thereof are soldered together at their junctures.

i Positioned between the 'front and back walls -86 and 81 Iprovide a pair of `wire mesh members 93 and 94 which are `formed in serpentine shape similar to the wire mesh member 92. vThe front interior mesh 93 is `positioned so that the fori wardlycurved portionsthereof contact the front wall 86 in the same line asthe rear curved portions of the member `92 contact the front wall, and the member 94 is positioned so that the forwardly curved portions thereof contact the rear curved portions of the member 93, and the rear curved portions of "the member 94 contact the rear wall 81. i

Positioned in each of *the crenelations 89 I provide a wire mesh `member 95 which is similar to the other previously described mesh members,

and between the crenelations I provide :similar mesh members 95. The mesh members 95 extend from the inner-surface of one side wall 9i) to the innervsurface of the opposite wall and thel` mesh membersl extend from the outer surface of one side wall 9G of one crenelation to the outer surface of the side wall of the adjacent crenelation. The mesh members 95 and 9S, like the mesh members 92 and 93, are `positioned so that the adjacent curved portions thereof engage the same side wall 9B in the same line.

The mesh members 92, 93, 9d, 95, and 96 are preferably secured in position in the same manner as previously described in connection with the Wire mesh members of the device lil.

The distance between the inner surface of the front wall 3o and the inner surface of the rear wall 8l 'is preferably twice the distance between the inner surfaces of the side walls Si! of the '-'1 With the conduit thus constructed, the size of the serpentine formation of all the mesh 'members S2, 93, gli, 95, and 96 is the same.
